Effects of the hydrous domain in the mantle wedge on magma formation and mixing at the Northeast Lau Spreading Centre, SW Pacific


Major and trace element concentrations of young volcanic rocks from the Northeast Lau Basin in the SW Pacific Ocean, as well as Sr-Nd-Hf-Pb isotope compositions. Analyses were mainly carried out at the GeoZentrum Nordbayern, University of Erlangen, Germany, where major elements were determined by electrons microprobe on volcanic glasses and by XRF on whole rocks. Trace elements were analyzed by LA ICPMS on glass at the Macquarie University, Sydney, Australia, and by dissolution ICPMS at the GeoZentrum Nordbayern. Water concentrations on glasses were analyzed by SIMS at the Australian National University, Canberra, Australia. Isotope ratios were determined by TIMS and MC ICPMS at the GeoZentrum Nordbayern.
